WebbPrincipal component analysis is a fast and flexible unsupervised method for dimensionality reduction in data, which we saw briefly in Introducing Scikit-Learn . Its behavior is easiest to visualize by looking at a two-dimensional dataset. Consider the following 200 points: In [2]: WebbComponent labels. predict_proba (X) [source] ¶ Evaluate the components’ density for each sample.
